u mercially termed or catalogued'as pusher linger-blades and 1n common shop parlance as back-kickers, such peculiar form of each linger-blade being composed of a flat finger or blade that is flexibly mounted under retractile spring tension on a transverse rockbar at the tail or delivery end of acylinder press and adapted to lie flat or horizontally in the press until the sheet-carrier reaches a point in its onward or forward deliverystroke where said rock-bar is timed to make a quarter-turn so as to bring the blade to an upright position immediately backjof kthe rear edge of the freshly-printed sheet that is in motion toward its final deposit on the delivery-board, and thereby preventing the said rear edge of said freshly-printed sheet reacting backwardly when electrostatic or like undue conditions are present beneath the sheet and retard its full seating or deposit in evenly piled form and unsmeared condition on said delivery-board, and thus also preventing said sheet moving backwardly into the press for crumpling or crushing therein and .n i

Asheet-carrier type ofcyllnder printing-press otherwise choking it up for retarding the further proper advance of succeeding'freshly-Y printed sheets, and said iiexiloly mounted blade hein g also adapted to be depressed on its hinge joint into horizontal or prostrate position so that the end cross-bar of the backwardly moving sheet carrier-frame, on its return stroke, will ride freely over the otherwise` normally prostrate iingerfblades and kready for the next forward or advance stroke of the freshly-printed sheet-delivery devices,

and thereby performing the most essential feature of my invention herein of having the sheet-carrier retreat Without anyliability or danger of breaking any of the said upright linger-blades after setting-action on the sheet and that has been very materially wanting in the use of the stift` andinflexible rubber or fiber 'blades heretoforein general, extensive use and quite" frequently fractured vand broken Yoff when theirniounting rock-bar ehanced tofail to rock onwas improperly t timed inthe adjustment ofthe machine by the press attendant, thereby causing considerable expense in Vsuch vbreakage and much .losSfOftimein the use 'of the P'eSSvaS Wen as'delay in' getting out orders.
